Hi.. From what I understand, for the payment options of a paid app on iTunes, Apple does accept -
Credit Cards or Debit Cards
Cheque
Bank Transfer
Credit Card Instalment
However, I Bought and installed this
app onto my iPhone 4, but it did not prompt me to select a payment mode or key in my Debit card details. Why is that so? Will I receive a notification or some form of billing or something for a "Free" app purchase?
